Need an assist on the Logun S16

I'm loving this rifle, but I see a minor problem with how it's adjusted. See the attached spreadsheet. I'm not familiar with how to get into this rifle, and my first rule is do no harm (no, I'm not a doctor, I just play one ) Anyway, it has been suggested that I need to reduce the pre-load on the hammer spring. Also, maybe I just need to back the hammer off a bit. Either way, it's striking too hard and releasing too much air. Any Logun S-16 owners out there past or present got a tutorial for getting into this fine PCP?
thank you,
darryl
